I suffered obesity all my life.  I ended up having a gastric bypass.  That was very successful for me.  For your son though, no motivation is hard.  Your first thing to do is to try to change his eating habits.  This is very hard because I am starting

to have the same problem with my daughter, who is 16.  She plays sport but eats too much of the wrong food.  I am now cutting out slowly junk food, biscuits, crisps, lollies and cakes.  Doing slowly will enable your son to be weaned off the junk food.  It will take time but if you slowly introduce the right foods, like fruit and vegetables, he will slowly lose the weight, thereby getting a bit more energy to start going for walks.  You need to start slowly because if you change suddenly, it wont work.
